Not sure about where to put the screen, but that is sure one ugly head unit.
I had thought about mounting to that big handle a little bit...didn't know what I would use though, but the RAM mounts are pretty damn cool. The best would be if I could have a clamp type piece on that handle, then a ball joint and then the screen, that way its fully adjustable. I didn't see any clamp stuff on that page at first glance though, looks like most of it is setup for drilling/attaching with screws. Maybe I will try to call them and see if they have something like what I need.
